THE NAUTILUS
You must have seen submarines on TV or in journals. These vessels, which
are capable of operating far below the surface of the sea without being
noticed, are used in ensuring national security and in some scientific re-
search. How submarines operate is: As the special diving tanks in a sub-
marine are filled with water, the vessel becomes heavier than water and

Now we will examine the nautilus, a very interesting creature that em-
